Counting Blank Spaces in string (Stupid question) 3

[Edge118]

$data = "Hello There";

How do I count the number of spaces in the string $data?

I know this is an easy question and I was reading through the posts that had questions similar to this, but I couldn't comprehend. Thanks.

Hi Edge,

you should be able to count the number of spaces in $data by applying the following:

++$count while $data =~ /\s/g;

hope this helps..

I think this will work:

$count = ($data =~ tr/\s/\s/);

Should this be:

$count = ($data =~ tr/ / /);

From [tt]man perlop[/tt]:
Note that "tr" does not do regular expression character classes
such as "\d" or "[:lower:]".

From what I deduce that [tt]\s[/tt] is not recognized in [tt]tr[/tt].

If you really need [tt]\s[/tt] (i.e any spacing character) use parkers' solution.

I actually did see that line in perlop but still tested with the \s and it worked fine. BUT, it looks like I didn't test very well and it was random chance I got the right count. Good catch Denis!
